Description

Tuftsin: N(2)-((1-(N(2)-L-Threonyl)-L-lysyl)-L-prolyl)-L-arginine. A tetrapeptide produced in the spleen by enzymatic cleavage of a leukophilic gamma-globulin. It stimulates the phagocytic activity of blood polymorphonuclear leukocytes and neutrophils in particular. The peptide is located in the Fd fragment of the gamma-globulin molecule.

Dosage Studied

Single administration of the regulating peptide tuftsin Thr- Lys-Pro-Arg (300 micrograms/kg) was shown to affect the state of the transmitter systems in the brain of rats treated with the sedative drug haloperidol. These results suggest that BL/LL macrophages exhibit a premature inability to undergoTuftsin stimulated microbicidal activity, which may possibly be reversed by serial dosage.

Drug Classes (1)

ClassDescription
peptideAmide derived from two or more amino carboxylic acid molecules (the same or different) by formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another with formal loss of water. The term is usually applied to structures formed from alpha-amino acids, but it includes those derived from any amino carboxylic acid. X = OH, OR, NH2, NHR, etc.
